KMC - DIGITAL CHAIN CHECKER

A patented pro tool of choice for bike shops and serious riders. Scientific, digital and precise.

KMC's digital chain checker takes chain evaluation to the next level by accurately quantifying the wear in a precise, repeatable method. This custom digital micrometer measures up to 2.5mm of elongation over four full chain links, and is accurate to 1/100th of a millimeter. Features include an on/off switch, zero calibration, metric/imperial switch, and a slide lock screw. The face is printed with clear wear ranges for quick evaluation of chain wear. Each digital chain checker includes a protective case, two LR44 batteries (one for initial installation and one spare) and a screwdriver to access the battery compartment. 

This chain checker is compatible with all 1/2" pitch chains from single to 11 speed, and functions well with chains from all manufacturers, including Campagnolo, SRAM, Shimano, and KMC.
